Finally got my first inboard boat, 1995 sport nautique with 2nd generation FCT, and perfect pass. Got it late season so didn't get it out more than a couple times before it got too cold. Does anyone know what is underneath or how to access the box structure that takes up space on the drivers side of the bow under the playpen seating? To me it looks like it takes up about 1/3 of the space underneath there. Trying to figure out how to weight it to get a good wake. I don't need a massive wake but would like a good solid one that will kick you up in the air a ways. I Was thinking of getting a fat seat to stick in the back in place of the back seat. Then getting a sack to put under the play pen bow and one in the ski locker. What size fits well in those two places? I am hoping this may give enough weight while allowing enough room for people and stuff.
